Hi Cascardo,

(In reply to comment #19)
> We are working on getting those fixes to 16.04, on the -updates repository.
> But it's not part of 16.04.4.

I am not sure I understood the following statement. Do you mean that the
fix will be pushed to -updates archive after the 16.04.4, thus, it will
not make the 16.04.4 cut date?

If that is the case, that might cause some impacts,  because we are
making a release that contains some known regressions. Should we
document it somewhere?

Thank you,
Breno
